Aesop's Fables, translated by Laura Gibbs (2002)

Zeus had decided to award prizes to the most beautiful animal babies
so he inspected each and every one of them in order to reach a decision.
The monkey also participated, claiming to be the mother of a very beautiful
baby: a naked, snub-nosed little monkey whom she cradled in her arms.
When the gods took a look at that monkey, they all started to laugh but
his mother insisted, 'The winner is for Zeus to decide! But in my eyes
this one is the most beautiful of all.'

Note: An epimythium probably added by a
later editor reads: 'This story has the following meaning for everyone,
in my opinion: each person thinks that his own child is beautiful.'
For the beauty contest of the animals, see Fable 329
and for another fable about the monkey and her offspring, see Fable
497.
